How to Eliminate Buddy Punching on Construction Sites in the UAE

Buddy punching — one worker clocking in on behalf of another — is one of the most persistent forms of time theft in the construction industry. On large UAE construction projects with hundreds of workers spread across multiple sites, the problem can be difficult to detect and expensive to ignore.

What buddy punching costs

Industry estimates suggest that buddy punching and related time theft account for 5 to 10 percent of total payroll costs. For a UAE construction company with 500 workers averaging AED 3,000 per month in wages, that translates to AED 75,000 to 150,000 in monthly losses. Over a year, the figure can exceed AED 1.5 million — money paid for hours never worked.

Why construction sites are vulnerable

Several factors make construction uniquely susceptible to buddy punching. Large crew sizes mean supervisors cannot personally verify every arrival. Multiple active sites make centralised oversight difficult. Subcontractor arrangements add layers of separation between the paying company and the individual worker. Shift handovers at dawn or dusk create low-visibility windows. And paper-based or basic card-swipe attendance systems are trivially easy to manipulate.

The limits of traditional solutions

Many construction companies have tried fingerprint scanners, but these face practical challenges on-site. Workers with calloused, dusty, or wet hands produce inconsistent reads. Hardware exposed to sand, heat, and humidity degrades quickly. And installing fixed readers at temporary or evolving site perimeters is impractical. Card-based systems are even weaker — a card can be handed to anyone.

Solution 1: Face recognition at check-in

Mobile face recognition requires the worker to take a selfie at the moment of check-in. The system compares the image against an enrolled photo using AI matching algorithms. This approach verifies identity without physical hardware, works in outdoor environments, and is difficult to spoof — the person must physically be present and facing the camera. Accuracy rates in good lighting conditions are approximately 98 percent with modern systems.

Solution 2: GPS geofencing

GPS geofencing creates a virtual boundary around each construction site. Check-ins are only accepted when the worker's phone is within the defined perimeter. This prevents remote check-ins — a worker cannot clock in from home or from a different site. When combined with face recognition, the system confirms both who is checking in and where they are standing.

Solution 3: Real-time alerts and dashboards

Automated alerts notify site managers when expected workers have not checked in by a defined time, when a check-in attempt fails face verification, or when a check-in is attempted from outside the geofence. A centralised dashboard gives project managers visibility across all sites simultaneously, replacing phone calls and manual head counts with real-time data.

UAE labour law context

Under UAE Federal Decree-Law No. 33 of 2021, employers are required to maintain accurate records of working hours and compensate employees accordingly. For a broader view of attendance and compliance challenges in the sector, see our guide on construction workforce management in the UAE. The Wage Protection System (WPS) mandates that wages match contracted hours. Inaccurate attendance records — whether from buddy punching or poor tracking — can lead to WPS non-compliance, MOHRE penalties, and disputes during labour inspections. Eliminating time theft is not just a cost issue; it is a compliance requirement.

Implementation considerations

When deploying an anti-buddy-punching system on construction sites, consider internet connectivity (the system should support offline check-in with later sync), worker training (keep the check-in process simple — one tap and a photo), device policy (company-issued phones or personal devices with a managed app), and data privacy (inform workers about what data is collected and how it is used, in compliance with UAE PDPL).
